I've so enjoyed the amazing Sun Gold cherry tomatoes from my garden this summer that I thought I'd try saving some for later in the year. On Saturday I dried some in the oven in the simplest way: washed them (here is a mix of the Sun Golds with some good-but-not-as-wonderful red grape tomatoes), cut them in half, and set them cut side up on a baking tray I'd brushed with olive oil. I didn't salt them or sprinkle them with herbs, though one can do that.
After about four hours at 210 F. the tomatoes above had turned into the tomatoes below. That wasn't a scientically determined length of time, and was too long for some of the smaller tomatoes. While most were still somewhat soft and leathery, some had actually turned brown and crispy -- tomato chips!
Here (below) is a closer view of tomatoes after drying. I let them cool, scooped them into a one-quart zip-lock bag, and popped them into the freezer. It seemed a remarkably small amount of dried tomatoes for such a large tray, but it's certainly several recipes' worth. They can be rehydrated in hot water, broth or wine, and then soaked in olive oil if desired.
I'd never tried drying anything before, so please don't consider me an expert in this! Next time, I think I'll pack the tray fuller, start checking them sooner, and remove ones that are done while leaving others in to get more drying time. Or maybe I should invest in a food dehydrator, which is probably more energy-efficient and operates at a lower temperature than my electric oven.
